Is my Suzuki XL7 3.6 timing chain stretched if I have code P0008?

Short answer: On the 2007–2009 XL7, the 3.6L V6 (shared with several GM models) is known for timing chains that stretch early. The usual first sign is the check engine light with code P0008 (or P0009, P0016–P0019), which means the computer sees the camshafts and crankshaft drifting out of sync. Suzuki issued an information bulletin (SI-0012R) with complete timing chain kits for this exact problem. It's a big repair, but catching it before the chain skips saves the engine.

Symptom: The check engine light with P0008, P0009, P0016, P0017, P0018 or P0019, a rattle for a few seconds at cold start, rough idle, or reduced power.

What to check first

1. Scan for codes. P0008 and its relatives on this engine point first to stretched timing chains.
2. Check the oil level and condition. Timing chains depend on clean oil at the right level, and low or old oil wears them faster.
3. Listen at cold start for a rattle from the front of the engine.
4. Ask the shop about Suzuki bulletin SI-0012R and the timing chain service kits it lists, so all the chains and tensioners are replaced at once.

Likely causes

1. Stretched timing chains. The chains wear and lengthen, so cam timing drifts and the computer sets P0008-type codes. Suzuki's bulletin says these codes from stretched chains are fixed with its chain kit.
2. Low oil level or overdue oil changes. Timing chains depend on clean oil, so poor oil maintenance can speed up chain wear.

What it usually costs

We couldn't confirm any owner-reported totals, so get a written quote. Suzuki's bulletin says its service kits include the chains, tensioners and gaskets normally needed. Ask the shop whether it's using the full kit.

Is it safe to keep driving?

You can usually drive short distances with P0008, but don't put it off. A badly stretched chain can skip a tooth and cause serious engine damage. If the rattle gets louder or the engine runs rough, stop driving and have it towed. Verify with a mechanic.

DIY or shop?

Shop. This is a front-of-engine timing job with special cam-locking tools. Experienced home mechanics do it, but most owners should use a shop.

Recalls, bulletins and complaints in plain words

• No recall covers the XL7 timing chains in NHTSA's recall data.
• Suzuki information bulletin SI-0012R (2007–2009 XL7, issued June 14, 2013): Suzuki created two timing chain service kits for 3.6L engines that set P0008, P0009, P0016, P0017, P0018 or P0019 because of stretched chains. The bulletin says the kits include the parts normally needed and that warranty claims must use the kit. This is a repair procedure, not free coverage.
• NHTSA complaints: 41 keyword-matched complaints for Suzuki XL7 2007–2009 (of 217 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-19; keywords: timing chain, chain, rattle, check engine, p0008, p0017).

What owners report

• Suzuki Forums' long-running Timing chains a MAJOR problem!! thread is where second-generation XL7 owners discuss timing chain trouble.
• In 2008 xl7 timing chain issue, a 2008 XL7 owner asked about a timing chain problem.
• In Suzuki XL7 engine light on, code P0008, an XL7 owner asked about a check engine light with code P0008, the timing-related code covered by Suzuki's bulletin.

My take

My advice as a former pre-purchase inspector: on any XL7 with the 3.6, I scan for codes and ask for oil change records before anything else. A clean scan and regular oil changes are what I want to see. If there's a P0008 history and no chain job on the records, I price the repair into the offer.

Safety / mechanic note

A badly stretched chain can skip and damage the engine. Verify with a mechanic.
